Our Transmogrification guides have been updated for Patch 5.2. This means that all the new items from Patch 5.2 have been added. We also added the Tier 15 and Arena Season 13 sets, as well as the Challenge Mode armors. Finally, Arena Season 9, 10, 11, and 12 sets are now obtained slightly differently than before, so the guides were updated to reflect that.
For our Patch 5.4 update, we will work on getting our model screenshots from the WoW Model Viewer, so that we can give you the option to display the models the way they look for female characters as well as for characters of all possible races. We may even be able to show items the way they will look in Shadowform.
So, stay tuned ;)
